That would imply that the block castings are different. Are you sure the mounts are not removable/interchangeable?I don't think they are interchangeable.
The engine mount on the front of the engine (harmonic balancer side of the engine) in the XC90 is on the lower part of the engine (next to/below the harmonic balancer).
I believe, in the S80, the front of the engine is supported higher up.
Lol.... Nailed it!Well, I see the problem now, the red dipstick isn't interchangeable with the yellow.
From what I can tell that upper mount on the S80 just bolts to the same spot as the lifting point on an XC90.
Here is the end of an XC90 engine which has the lifting point in place.
Here is a S80 engine, the 3 holes it uses are present on the XC90 block.
Another S80 engine
And replace the spark plugs in the rear and the oh so easy to get to with the motor in the car tensioner in the front.I looked at this as well yesterday, with another photo set here (as long as it lasts)- https://www.ebay.com.au/itm/V8-Yamaha-Volvo-Engine-4-4L-i-/272777756243
I see the mount holes for both cars on both the engines, the rear bank cooling brackets are the same between the two. At a high level, I cannot see anything overtly obvious that would prevent a swap.
For alternator, if you don't buy new at least consider swapping the regulator and brushes since you're already there.
If you dont mind me asking.... what failed on the motor?.... how many miles?I have an 05 XC90 V8 that has a bad engine, I'm shopping engines and the S80 V8's seem to go cheaper, does anyone know if they are interchangeable between the two models? The engine I'm looking at is from a 07 S80.
Not sure yet, I know the valves are bent, I'm assuming it's a balance shaft bearing that failed and let the chain go loose. I bought the car with the engine failed so I've yet to pull it out and find out what actually failed. It failed at 153K.If you dont mind me asking.... what failed on the motor?.... how many miles?

Reseal the upper & lower oil pan as well while you're at it. After that, you will have dealt with all the normal oil leak spots.Yes, my plan is to reseal the timing cover, valve covers, RMS and do a full tuneup outside of the car.
Thanks!Reseal the upper & lower oil pan as well while you're at it. After that, you will have dealt with all the normal oil leak spots.
Maybe (while it's on an engine stand), reseal the oil gallery plug that's above the RMS. If I remember right, it's something like a 14mm hex plug.
